RE: My LEDs
As far as I'm aware, the Auto White Balance setting on most cameras is simply somewhere shy of full, daytime sun. The camera doesn't actually choose. (At least that's the way it was last time I checked. Perhaps the tech has advanced since then.)
The camera's flash is in this ballpark.
So for example, if you take a photo at night, indoors, with incandescent lighting and no flash... you will notice your white walls looking pinkish orange (salmon?). The flash will generally go a long way to correct the color.
The only way to get accurate color is to use the Manual White Balance setting. You set it to a bright white sheet of paper in the same area as your subject... then shoot.
Still... I would think that if you turn the flash off and use AWB, you should still be able to capture a color difference, though the colors themselves may not be perfectly accurate.
As a side note... all those years you thought you were a great photographer and now you get weird colors with your shiny new digital camera. Must be the camera, right?
Well... the fine folks developing your film were correcting for color all along. And now it's up to YOU to perform that operation. Learn about white balance and you will take better photos.

RE: My LEDs
I have two single 921-bulb fixtures mounted vertically on the headboard. As a test I put a 36-1210 warm white LED panel in one, turned them both on, and asked DW for her opinion.
She thought the LED light was brighter than the 921 bulb and she didn't like it for over the bed. But in a dual bulb overhead fixture it was OK.
So, I ordered enough 36-1210 panels do do the overhead lights, and two 24-1210 panels for the headboard lights.Nice!
Give us an update sometime down the road, eh?

RE: My LEDs
I ordered one of these with the heat sink today. Also ordered 5 different ones from eBay seller 2011_led who has been very popular in this thread. When they arrive, I will do a comparison and post the results.
Sweet. That would be cool.
If anyone would like to help compile some of the latest hot items like this, I will update them to the OP.

RE: My LEDs
If I may beg an answer...
Has there been any uncontroversial or uncontested CONCLUSIONS in 15 pages of this thread? I'm serious, and this is meant to be polite...
15 pages???
You're using the 20/pg setting. It's a whopping 29 for me!
The OP is still the most succinct set of data, but there are findings throughout the thread.
Unregulated panels are known to pop LEDs on occasion. The can also heat up and fall when the tape adhesive liquifies.
Regulated bulbs (probably panels too) with voltage ranges like 10-30 have been pretty thoroughly vetted and appear to last quite a long time.
Regardless, at today's prices, for the boondocker, LEDs are pretty much a no-brainer.
Chinese ebay prices are tough to beat. Figure 2 weeks deliver to the states. No idea how long to Bungfleck, Mexico.
Is this close enough to what you were looking for Gramps?

RE: My LEDs
Has anyone tried these from M4Products.com?
http://www.m4products.com/double-aluminum-plate-in-warm-white-10-30v/
I have just read all 28 pages of this thread to learn as much as I can from everyone else's experience before converting my 921's to LED's. Just got my first TT 2 weeks ago, and am still learning about it all.
Hmmm. Heat sink design. I like the idea. Price seems reasonable with that in mind. I paid more for my first panels... "back in the day" (way back 2 years ago or whatever it was. :) )
It has 5050 SMD LEDs. Should be plenty bright. 16 LEDs * 15L ea = 240 Lumens. That's about equal to one of my 1141 incandescent bulbs; medium bright, but focused toward the room.
I have buck regulated bulbs and I don't notice any RFI over AM channels. I believe it is more a problem for Ham guys than it is the rest of us.
I say be our guinea pig; give one a try and report back! Be sure to check for RFI.

RE: My LEDs
...I'm not judging anything by the cover ...
You misunderstood me, Falcon. Duck... was the one whom I believe was judging the book by its cover... by calling out your LEDs as of low quality... likely based on the recent photo... having not seen your better representation from the earlier post.

RE: My LEDs
They sure do look like a poor quality LED.
DonHow can you tell?
He can correct me if I'm wrong, but I'm guessing he is judging the book by it's cover. The camera that took that shot was metered to compensate for the brightness of the bulb (or in this case... the lit LEDs) by either a small lens aperture, high shutter speed or combination of the two. The resultant photo is not representative of what the eye would see if it were in the room.
Falcon,
Don't sell 'em all. Like any lightbulb, they WILL die at some point. Good to keep some spares on board.

RE: My LEDs
Nice! And a heckuva' price!
I recall being happy to score my bulb-style lamps for more like 15 clams. I like these better than the panels for a hair better heat dissipation.
I wonder if these are voltage regulated. If not, they may not last quite as long as regulated bulbs, but should still last plenty long for some serious enjoyment and peace of mind while boondocking.
If they are unregulated, you might notice a brightening when you switch from battery to converter power... and possibly more pronounced on alternator power. If you could try and decipher that and let us know, that would be great.
The Ham radio cats actually prefer the unregulated versions. The regulators emit a good deal of RFI.
Unregulated pros and cons:
Pro: No RFI
Con: Shorter life

RE: My LEDs
You guys are awesome here ... I could have never imagined so much help on all my questions I have had lately ... amazing community we got here. :)
It's true, we ARE pretty great. And overwhelmingly modest, too! :)
Yeah, the shipping time is the price you pay. But that little bit of patience sure did pay off for me. No longer is there any concern when my girls want to turn on a bunch of lights. And I like leaving the porch light on all night too!

RE: My LEDs
IMO, the 36-1210s are a little brighter than my 1141s. 24-5050s would be brighter still.
That said... I believe incandescent bulbs degrade in brightness over time and I have no idea how many hours were on my bulbs when I bought the rig.
So YMMV

RE: My LEDs
Sheesh, for prices like THAT... how can you go wrong???
Sure, some of the LEDs may pop down the road, but for $1.80, I think I can live with that. Plus with no regulator comes no RFI.
Only downside is they don't come with a BA15S adapter for older rigs like mine.

RE: PD or Iota for my upgrade?
Yep. Sal had noted this some time ago; Two entirely different algorithms in the PD and the IOTA, with some attention to safety, yield similar results when there is too much resistance. BFL's "Ugly Graph" comes off his Vectors. Nothing beats the Vector's algorithm, IMO, but with adequate cabling, the IOTA comes pretty close; especially for those who want to "set it... and forget it."
If you're not in any hurry, either the PD or IOTA will do you well enough. But if you want to really shorten your genny time, upgrade and/or shorten your cabling.

RE: CHINA And Deep Cycle Batteries
Yeah, China's rise to power and subsequent demand for raw materials is not a positive for the rest of us. But you may as well get used to it, 'cuz it's something we're going to have to live with for awhile, me thinks.
Regarding Mex's point about strategic materials... funny... until recently I ASSumed that more domestic oil drilling meant cheaper gas prices for the U.S. and greater energy independence from those who wish to do is harm. That is until last year when I heard that we had become a net exporter of oil. A lightbulb went off. "Oh yeah. Oil companies are private corporations... not government entities. They can pretty well sell to whomever will pay the highest price on the open market"... ergo... China is now buying some of our oil... and will be buying more once the new pipeline is in. And were it not an important strategic commodity that is drilled out of our public lands via permit, I would agree with the idea.
So next time someone tells you drilling is going to lower gas prices... you can kindly enlighten them so they need not be so naive as was I. Whatever more we produce next year over this will be, essentially divided over the whole of the planet's oil consumers. A few zillion more barrels might get you a a few cents off at the pump.
The real benefit of more drilling is more GNP and jobs. And right now... we could use some of both. But let's just see it for what it is and not what some politician tries to sell us.
JMHO
Now what were we talking about again???

RE: House battery and converter problem
IMO it is crazy to buy a MPPT controller for one 100w panel. The maybe 10% increase in daily AH haul , when that is 10% of not much, is peanuts, but the cost of the MPPT is not peanuts
1. I agree that the gains will be small, but as I said, MPPT would be right for someone with the extra funds, but not the extra roof real estate. Some people DO have money. I don't know any, but I see them on TV.
2. I believe 10% gains are more the rule for "12V" panels and higher gains may be had with a 24V panel.

RE: low voltage and PD converters
"For the system to use something like "2-3A" per battery, it would have to know how many batteries, yes?"
---------------
I think ( :( ) if the bank is bigger it just takes longer to get up to that same voltage, but when it does, it is at the same amps per battery
Well that I can wrap my head around. But of course there would be more Amps and there is no way for the unit to know that the bank is bigger. The only way I could see is if it kept track of the time it took. But then... if you were using power from the bank during the charge, it might look like a larger bank than it is.
I would be pretty surprised if it was something other than some kind of voltage trigger.
